Well, the same white men created Jim Crow and seggregation.

If you were a black man would you have been disenfranchised when those laws were in force?

I'd say yes.

The fact that it was/is worse elsewhere, e.g. in some places in Asia, doesn't make the critique (of how white Constitutional/law makers historically disenfranchised certain demographics in the US) invalid.

No, and politely, wtf is that logic?

You are disenfranchised when your judicial branch interprets law in a way that disproportionately benefits only the people who are most similar to the authors.

Also, how wealthy are you? Why did you bring up your race instead of how much land you own? Why pull the culture war into this? Certain interpretations of the constitution disproportionately benefit people who own a lot of land.

Those rights came to exist in the west in response to kings and tyrants doing whatever they wanted at the expense of their subjects. Also because communities sometimes do bad things to people not able to simply drive away. Pretty sure Asia has had it's share of human rights abuses.
